4.2 Thermal Design

Highly integrated modules like LEVY offer very high performance within small dimensions. On the other hand, the miniaturization of ICs and the high operating

frequencies of the processors lead to high heat generation that must be dissipated in order to maintain the CPU within its allowed temperature range.

The operating temperature specified in the Technical Features of LEVY module indicates the temperature range in which any and all parts of the heat spreader / heat

sink must remain, in order for SECO to guarantee functionality. Hence, these numbers do not necessarily indicate the suitable environmental temperature.

The heat spreader is not intended to be a guaranteed standalone cooling system, but should be used only as a supplemental means of transferring heat to another

dissipation system (i.e. heat sinks, fans, heat pipes etc).

It is the customer's responsibility to design and apply an application-dependent cooling system, capable of ensuring that the heat spreader / heat sink temperature

remain within the indicated range of the module.

It is an absolute requirement that the customer, after thorough evaluation of the processor's workload in the actual system application, the system enclosure and

consequent air flow/Thermal analysis, accurately study and develop a suitable cooling solution for the assembled system.

SECO can provide LEVY module specific heatspreaders and heatsinks, but please remember that their use must be evaluated accurately inside the final system,

and that they should be used only as a part of a more comprehensive ad-hoc cooling solutions.

Warning!

The thermal solutions available with SECO boards are tested in the commercial temperature range (0-60°C), without housing and inside climatic

chamber. Therefore, the customer is suggested to study, develop and validate the cooling solution for his system, considering ambient

In particular, the heatspreader is not intended to be a cooling system by itself, but only as the standard means for transferring heat to cooler, like

heatsinks, cold plate, heat pipes and so on.
